ALBERT KLINGER, OF BRADFORD, OHIO, ASSIGNOR OF ONE-HALF TO JOHN M. WESTOOTT, OF RICHMOND, INDIANA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 359,613. dated March 22, 1887.

Application filed November 18, 1886. Serial No. 219.314. (No model.)

'Vator constructed in accordance with my invention. Fig. 2 is a detail.I

My invention relates to improvements in Wheelcultivators, in which I use, in conneci tion with a frame and tongue, a spring, a lever, and amovable fulcrum for said lever, by

v the action of the beams or shovels.

which the same amount of lifting force is exerted on the shovel-beams, whether they are at Work or raised, or regardless of the action of the beams.

The objects of my improvements are, first, to have a continuous lifting-pressure on the shovel-beams, whether the beams are down or up, consequently helping the operator all the time second, to have the minimum of weight on the front end of the tongue, regardless of I attain these objects by the mechanism illustrated in the accompanying drawings, in which the parts are the 'same as on most plows, except as hereinafter described.

2 is a cross-beam bolted to the tongue or pole.

The numeral 3 indicates a lever jointed to the hanger 1 by the bolt 4., on which it works as a hinge.

5 is a brace. Y

6 is a coil-spring upon a vertical rod, 20, at its upper end secured to a cross-beam, 2", on the tongue, and its lower end supported by the bracket 21 on the arched axle 16.

7 is a movable fulcrum for the lever, and this fulcrum has an anti-friction roller at its upper end. This arm or fulcrum is connected to the axle-washer or Wedge-shaped sleeve 11 on the arched axle by passing through an extension, 22, of the washer.

12 is a coupling connected to the wedgeshaped part of the axle-washer 11 by jaws fitting rmly to it.

8 is a beam connected to the coupling 12 by a bolt passing through at 13.

By making the part 11 wedge-shaped I am enabled to connect it readily to the jaws of the coupling 12 without the use of bolts, and at the same time provide a coupling that will not wear,as it always wedges itself perfectly tight, thereby drawing and holding the dragbars to their place.

The lever receives the pressure of the spring at 10 and, is communicated to the fulcrum 7, thereby having a certain pressure on the front part of the washer 11; hence it presses the beam 8 up, or takes the weight of the beam 8 off the horses as the beam is lowered by the operator. The friction-roller on the end of the fulcrum moves toward the point 10 of the lever, and forces the lever at that point up, thereby increasing the tension of the spring, but also shortens the lever, and as the beam is raised again the friction-roller is driven toward the pivot or bolt 4, thereby lessening the tension of the spring, but the length of the lever becomes greater, thus having an even continuous pressure on the fulcrum 7, and the same amount ofthe weight of the beam, whether the beam is up or down, as the pressure applied on the fulcrum 7 is upward as well as downward,and that pressure is communicated to the tongue at 2 and by the coil-spring 6. By this pressure the weight of the tongue is carried, hence does not rest to any great extent on the horses7 necks. In the'above description I have coniined myself to one side of the machine; but of course it is to be understood that the other side is constructed in a similar-manner. f

What I claim as new is 1. The combination, in a wheel-cultivator,

of the frame, the drag-bars hinged thereto, a lever, 3, having a movable fulcrum, 7, and a spring acting upon said lever, as shown and described, whereby the spring is caused to exert a uniform lifting force upon the drag-bars and upon the tongue at the neck-yoke,whether the shovels are raised or down and at work. 2. The combination, with the frame and dragbars hinged thereto, of the cross-bar 2, lever 3, suspended from said cross-bar, vertical rod 20, spring 6, encircling the same and acting on said lever, and a movable fulcrum for said lever, substantially as and for the purpose specified,
